Materials Data on Eu(ZnSi)2 by Materials Project
EuZn2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Eu is bonded in a 8-coordinate geometry to eight equivalent Zn and eight equivalent Si atoms. All Eu–Zn bond lengths are 3.33 Å. All Eu–Si bond lengths are 3.24 Å. Zn is bonded to four equivalent Eu and four equivalent Si atoms to form a mixture of distorted edge, face, and corner-sharing ZnEu4Si4 tetrahedra. All Zn–Si bond lengths are 2.54 Å. Si is bonded in a 9-coordinate geometry to four equivalent Eu, four equivalent Zn, and one Si atom. The Si–Si bond length is 2.37 Å.
